WINDMILL.

SPECIFICATION forming part of Letters Patent No. 423,602, dated March 18, 1890.

Application filed May 2'7, 1889. Serial No. 312,217. (No model.)

' To all whom it may concern.-

hereby declare the following to be a full, clear,

and exact description of the invention, such ,as will enable others skilled in the art to which it appertains to make and use the same.

The invention has relation to Windmills, and has for its object certain improvements in the construction of the wheel, the sails therefor, and the mechanism for transmitting a rotary motion of the wheel, which will fully appear hereinafter.

-With the above-recited object in view my invention consists in the construction and combinations of parts, as hereinafter fully described, illustrated in the drawings, and pointed out in the claims.

In the drawings, Figure l is a top view of my improved mill. Fig. 2 is a side elevation of same, partly in section. Fig. 3 is a detail View of the wheel. Fig. 4 is a perspective view of one of the blades. Fig. 5 is a front view of the mill, partly broken away.

Referring to the drawings by numbers, 1 indicates the mast for supporting the wheel and operating mechanism, said mast being composed of four sections 1, secured together in a rectangular form. Said mast is provided at its lower end with the cylindrical portion 2, which is adapted to fit within a socket in the cap of the tower. Secured upon the upper end of the mast is thecasting 3, upon the upper face of which are secured the bearings 4 for the wheel-shaft 5. One end of said shaft carries a crank-wheel 6, to the crank 7 of which is pivoted the upper end of the rod 8, which passes down through the mast and.

converts the rotary motion of the wheel into a reciprocating motion for pumping and other purposes. The lower end of said rod is secured to a pin 8,located in a recess in a rectangular block 9. To the lower end of the block 9 is secured the rod 9, which passes down within the tower and serves as a continuation of the rod 8. The block 9 is designed to guide the rod in its reciprocating movements.

- 1O is'the wind-Vane, provided with the arms 11, which are pivoted to the casting 3 upon a pin 12, as shown.

13 is the governor-vane, of any preferred construction, which passes through a slot 14, formed in an arm 15, secured to the mast and braced by means of the arms 15, and has its inner end pivoted to the side of casting .3. The governor-vane is provided with aweight 16, secured upon the rear face thereof, the tendency of which is to cause the said vane to always be in a lowered position to hold the wheel out of the wind, and in order that the said vane may control the wind-vane in said movement a chain 17 is secured at one end to the arm 14. of the governorvane, passes over a guide-pulley 18, pivoted upon, the arm 15, and is secured at its other end to one of the arms 11 of the vane 10. For operating the latter vane to bring the wheel into the wind and simultaneously raise the governor-vane I provide a chain 19, which is secured at one end to the arm 11 of vane 10, passes over a horizontal guide-pulley 20, pivoted in a slot 21 in the outer end of the arm 22 of casting 3, thence over a vertical guide-pulley 23, pivoted to the side of said arm, and secured at its other end to the upper end of a rod 24, which passes down through the mast and through the block 9, and secured at its lower end to a sleeve or collar 25, which is loosely mounted upon the rod 9, which serves to properly guide said rod in its vertical movements.

For operating the rod 24 from a point within the tower a rod 26 is provided, which is secured to the sleeve 25 and has the looped portion 27, which encircles the rod 9 and which carries at its lower end an operatinghandle. (Not shown.)

28 is the wheel, which is mounted upon the outer end' of the shaft 5. Said wheel is provided with the hub 29, into which are fitted the inner ends of the arms 30, which are passed through slots in the ring 31. The outer ends of said arms 30 are provided with openings, for a purpose presently explained.

33 indicates the improved sails, which are constructed as follows:

34 and 35 are. two fiat tapering sections ner to form an obtuse angle, as shown. Each of the sections is providedat its lower end with a semi-cylindrical tenon 37, which, when the sections are secured together, form a cylindrical tenon, which fits within like openings in the ring 31. To strengthen and hold the sections 34 and 35 together, a knee-brace 38 is provided, secured to said sections.

The brace 38 is provided with a recess into which is fitted one of the sections 39 of the rim 40, and to adapt said section to be readily secured to the brace the sections 34; and 35 of the sails are cut away to form an opening or slot 33 for this purpose. When the sails are placed in position, the rim-sections pass through the openings 31 in the arms 30, as shown. Each of the rim-sections is provided upon its upper face with a groove, into which,

when the sails are secured in position in the wheel, fits a metallic band 41, threaded at its ends, a coupling 42 serving to draw the ends together and tighten the sections in place.

It will be seen that when the wheel is in the wind the vane 10 will stand at an acute angle to the wheel instead of at right angles thereto, as is the case with windmills as or dinarily constructed, so that the wheel will also stand at an acute angle to the direction of the wind, in order that the wind maystrike the sails directly and the full force thereof be exerted upon said sails.

To limit the throw of the vane 10 when being brought into the wind, I provide a stop 50, secured to the casting 3, against which will abut one of the arms 11 of the vane 10.

Having fully described my invention, what I claim, and desire to secure by Letters Patent, is i 1. In a windmill, the wheel 28, having the hub 29, into which fit the arms 30, the ring 31, provided with slots for-the passage of said arms, the sails 33, consisting of the sections 34 and 35, arranged at an angle to each other, as described, the braces 38, provided with recesses, a tenon at the lower end of the sails fitting within sockets in said ring 31, and the rim-sections 39, fitting'within the recesses in the braces 38, and the clamping-band 41, passing around said rim-sections, and a coupling uniting the ends of said band, said parts being arranged substantially as described.

2. In a windmill, the sail 33, consisting of the sections 34: 35, secured together at their .edges 36 to form an obtuse angle and cut away at top' to form a slot 33', the tenon at the lower end thereof, the knee-brace 38, recessed, as described, and the rim-section 39, fitting within said recess and within the slot or opening 33', all arranged substantially as specified.

3. In a windmill, the combination, with the revoluble hollow mast and the wheel carried thereby, of the casting carried by said mast, the wind-vane pivoted to said casting, the governor-vane pivoted to the side of the mast,

a rigid weight secured to said governor, a

flexible connection between said vanes, a chain connected to the wind-vane and passing down within the mast, a connection between said chain and a suitable operatinghandle, and a stop secured to the casting on the upper end of the mast for limiting the throw of the wind-vane when-brought into the wind, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
